WHAT IS SUCCESSFUL PROTOTYPING? INSIGHTS FROM NOVICE DESIGNERS’ SELF-EVALUATION OF PROTOTYPING SUCCESS

Abstract Prototyping is essential for fuzzy front-end product development. The prototyping process answers questions about critical assumptions and supports design decisions, but it often unstructured context-dependent. Previously, we showed how to guide novice designers in early development stages with milestones. Here, studied the success perceived by teams. This was done two steps: (1) teams were asked assign each prototype a milestone, specific purpose, fidelity level, human-centered lens, then evaluate using predefined set of criteria. (2) Teams interviewed process, this time self-chosen Results related show that activities respect desirability problem validation significantly less successful than towards feasibility solution validation. mostly chose criteria well prototypes supported communication, decision making, learning, tangibility. insight may be used give priorities further improvement methods guidance these areas.
